#### Example 2: Using the GetVariableValue and SetVariableValue Methods to Pass Variables

The following example first uses PC-DMIS code to receive an integer value from the user and assigns it to the V1 variable.

C1=COMMENT/INPUT,Please type an integer value.

ASSIGN/V1=INT(C1.INPUT)

COMMENT/OPER,BEFORE SCRIPT: Variable is:

,V1

It then calls a BASIC script named TEST2.BAS.

CS1=SCRIPT/FILENAME=D:\PROGRAM FILES\PCDMIS35\TEST2.BAS

FUNCTION/Main,SHOW=YES,,

STARTSCRIPT/

ENDSCRIPT/

Here is TEST2.BAS:

Sub Main

Dim App As Object

Set App=CreateObject("PCDLRN.Application")

Dim Part As Object

Set Part=App.ActivePartProgram

Dim Var As Object

Set Var=Part.GetVariableValue("V1")

Dim I As Object

If Not Var Is Nothing Then

Var.LongValue=Var.LongValue+1

Part.SetVariableValue "V1",Var

MsgBox"V1 is now: "&Var.LongValue

Else

Msgbox"Could Not find variable"

End If

End Sub

This script takes V1 variable and, using the GetVariableValue and SetVariableValue automation methods, increments the V1 by one and then sets the new value for V1 in the measurement routine.

PC-DMIS then displays the changed variable in an operator comment.

COMMENT/OPER,AFTER SCRIPT:Variable is now

,V1
